| Dugupi-Maanshan Sb deposit, Niujie, Weishan County, Dali Prefecture, Yunnan Province, China |
| Miniature | 4.5x3.5x3cm | 50g |
| Light purple, strongly phosphorescent fluorite! Columnar structures represent perimorphs after stibnite, which completely vanished into bright white secondary antimony minerals that are present on this specimen as well. Not analyzed and preliminarily named here "stibiconite", there are strong hints that rarer secondary Sb-minerals, such as coquandite are present. Opaque white areas on the fluorite lining the stibiconite pockets may in fact be inclusions related to antimony content, as the "whitest" fluorite xls occur in immediate vicinity of the Sb-minerals. Bubbly transparent surface structures on the fluorite xls, (which often look like edge damages!) cause a green shortwave fluorescence with noticeable phosphorescence in the otherwise blue fluorescent fluorite. It is yet unclear if these are inclusions or surface coatings. The overgrowth on some fluorite consists mainly of light brown, corroded calcite scalenohedrons, aragonite (bright white balls) gypsum and secondary antimony minerals. Found 2009. |

| Light purple fluorite with yellow coating of varying iridescence! The columnar structure of the aggregates represents a perimorph after stibnite that completely vanished into secondary, usually pure white to pink antimony minerals. Not analyzed and preliminarily named here "stibiconite", there are strong hints that rarer secondary Sb-minerals are present, such as coquandite. Opaque white areas at the inside of the columns may in fact be inclusions related to antimony content, as the "whitest" fluorite xls occur in immediate vicinity of amorphous secondary Sb-minerals. Translucent surface minerals, usually along the edges of the otherwise transparent fluorite xls (which often look like edge damages!) cause a green shortwave fluorescence with noticeable phosphorescence in the otherwise blue fluorescent fluorite. Yellow effects are caused by whitish fluorescence shining through the yellow surface coating. The unilateral overgrowth on the fluorite column consists mainly of light brown, corroded calcite scalenohedrons, aragonite (bright white balls) and secondary antimony minerals. Found 2009. |

It is yet unclear if these are inclusions or surface coatings. The overgrowth consists mainly of light brown, corroded calcite scalenohedrons, aragonite, gypsum and secondary antimony minerals.
